Sleep Longitudinal Exploration of the Experience of Patients

France1,000 participantsStarted 2025-04-23

Plain-language summary

Many epidemiological studies report that insomnia is common after fifty years in the general population but also in the post-operative period of surgery. Preoperatively, sleep quality can be disturbed by fear of general anesthesia and surgery. Postoperatively, it seems to be altered by pain, the ambient environment and night care. Literature shows that the occurrence of post-operative sleep disorders seems to lead to (increased) hypnotic consumption in patients who did not consume them in the pre-operative phase with known risks of dependence. Nowadays , general anesthesia is widely practiced worldwide. However, despite continuous improvement in techniques, a large number of patients still experience poor quality postoperative sleep, even with short-term anesthesia. It therefore appears that general anesthesia disrupts the circadian rhythm of patients, even if the mechanisms are still poorly understood. Thus, sleep deprivation could be responsible of physiological alterations that are still unknown, such as delayed healing or impaired respiratory muscle performance, promoting postoperative complications. The aim of this study is to identify the factors impacting the quality of sleep of patients undergoing scheduled surgery during the first postoperative night. And its implication on the occurrence of drowsiness described by the patient the day after their surgical intervention.

Inclusion Criteria: * Male or female subject aged 18 years or older; * Subject scheduled to undergo surgery under general anesthesia (orthopedic, thoracic, vascular or visceral surgery); * Subject able to complete a self-administered questionnaire; * Subject having given oral consent; Exclusion Criteria: * Subject wishing to discontinue participation in the study before the end; * Subject for whom the surgical procedure could not be performed after admission to the operating room (whatever the reason); * Subject for whom the surgical procedure was performed urgently before the date initially scheduled (whatever the reason); * Subject for whom a serious perioperative complication occurred during the surgical procedure

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
